Adding Sub/amp Ipod

[ZR1Vette09]

Hey guys, looking for a little bit of guidance as I don't have a wiring diagram for this year. I'm adding a sub and amp to the factory Bose system in my 05 Crew Cab. Just for fun tonight i tore my way down to the amp and I'm curious if anyone knows exactly the location of the wires I need. Here's what I was looking at:

 

 

The right of the picture being towards the front of the truck. My assumption is that the wires I need are in the blue clip seen here:

 

 

I've ordered a scosche LOC to do the job, but as I said I don't have the wiring diagram. Can anyone help me out with which wires lead to the factory sub for my LOC and which acts as the accessory for me to use as a remote amp power.

I found this wiring diagram of that harness

but it does not show which pin is the output to the bose sub. Even if someone knows which color wires feed the sub that would help me out bigtime and prevent me from having to dig down to the sub just to find a wire.

Maybe this will draw a reply- found everything I needed except a good grommet to run my power cable through the firewall. Anyone know of a good location (and picture)?

If you look behind the fuse box located under the driver side dash you will find a circle cut out by the factory in the insulation. You will find a dimple on the firewall and thats were you can drill to run your power wire. I got a grommet with my stinger amp kit and they should have them at any quality audio shop.

 

PS: Be sure to check the engine side of the firewall to make sure its clear but mine was.

Just using the factory sub outputs is not going to work real well. The factory stereo is designed to drop the bass levels as the volume is turned up....it's a warrantee/blown speaker thing. There are interfaces available to correct this...all plug and play. I put a JL Stealthbox in the new 2010 this week with the proper interface and the sound is AMAZING. The interface isn't expensive....200 Canuck bucks retail....so probably 125-150 USD.
